[PATCH v6 0/1] MR11178: winewayland: Implement xdg-popup for unmanaged windows.
This patch significantly improves compositor behavior across various compositors, as popups are guaranteed not to get clipped at the window boundary. In addition, it enables server-side decorations to be implemented on the winewayland driver. To achieve this, I attempted to reuse as much of the exsisting xdg-toplevel code as possible. -- v6: winewayland: Implement xdg-popup for unmanaged windows. https://gitlab.winehq.org/wine/wine/-/merge_requests/11178
